Guide Entry to 25.04.05
Despite an inherent connection between cartography and mathematics, it seems that maps are rarely used as a tool to augment student learning in the Geometry classroom. This unit, Topographical Trilateration and Triangulation, focuses on the geometric makeup of Earth and the relationships of various points on Earth and in space to one another. The trilateration section of this unit will teach students how to identify unknown locations with both circular and spherical projections of distance from three or more known locations; the triangulation section will teach students how to identify unknown locations from two known locations and calculate unknown distance between two known positions. This unit should be taught at the culmination of Geometry as a means of reviewing various concepts from throughout the year, such as conversions, angle construction, and tangent, in a way that is both practical and tangible.
(Developed for Geometry, grade 9; recommended for Trigonometry and Precalculus, grade 11)
